1. An organopolysiloxane polymer having a glycerol derivative which can swell up by containing at least its own weight of a liquid oil selected from the group consisting of hydrocarbon oil, ester oil, natural animal and vegetable oils, semi-synthetic oil, and silicone oil selected from the group consisting of dimethylpolysiloxane, methylphenylpolysiloxane, methylhydrogenpolysiloxane and dimethylsiloxane-methylphenyl siloxane copolymer, cyclosiloxanes, branched siloxanes, higher alkoxy-modified silicones, alkyl-modified silicones and amino-modified silicones, wherein fluorinated silicones are excluded,
obtained by the addition polymerization of an organohydrogenpolysiloxane expressed by the following general formula R1dHeSiO(4-d-e)/2, with a glycerol derivative having alkenyl groups expressed by at least one of the following general formulae, wherein, R1 may be identical or different and is a substituted or unsubstituted monovalent hydrocarbon group having 1-30 carbon atoms which does not contain an alkenyl group, R3 is an alkenyl group having 2-20 carbon atoms, d and e are respectively defined by: 1.0≦d≦2.3, 0.001≦e≦1.0, 1.5≦d+e≦2.6, and s, t, u and v are respectively integers in the range 1-20; and wherein, the organopolysiloxane polymer has a three-dimensional cross-linked structure.
